Product Details

The COMP Cams 940-12 is a high-performance valve spring designed for racing and high-RPM engine applications. This outer valve spring features a 1.464-inch outer diameter and includes an integrated damper to reduce valve spring harmonics and flutter at high engine speeds.

Key Features:

  • 1.464-inch outer diameter for compatibility with larger valve spring pockets
  • Integrated damper design controls spring surge and harmonics
  • Precision-wound from high-quality chrome silicon steel
  • Heat-treated for durability and consistent tension retention
  • Engineered for high-lift camshafts and elevated RPM ranges
  • Ideal for performance street, racing, and competition applications

This valve spring is designed to work with COMP Cams performance camshafts and valvetrain components. The damper configuration helps prevent coil bind and maintains proper valve control even under extreme operating conditions. Sold individually.

Easy to use

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

Excellent on-line merchant with outstanding customer service and the best prices on equipment and shipping. Highly reccomended!

Good prices and easy ordering process (order #18003). The only issue that I had was after placing the order, completing the entire process, I received three emails stating that "We noticed that you started checking out on our site, but didn't quite finish the process". After calling customer service, they ensured me that the order was complete. Since then, I receive the same email(3 emails at a time) on a daily basis. Just a little annoying, but easy enough to delete.
